Replace Item at Index not working...again

Hello, I seem to have difficulty with this all of the time. I am trying to replace items in a list, In this case “false” with a list of variables that should occur the same number of times. However, rather than using the first index location to replace the first replacement sublist and the second index location to replace the second replacement sublist, it seems to get stuck on either the first index location or the first sublist location. I tried messing with my @levels and lacing quite a bit but cant seem to figure it out. Anybody got any ideas? (yes i did read many of the topics on list.replace item at index on this forum already today, none of them worked)
